Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion

Surface tension
Surface tension:
25.2 mN/m
Temp.:
25 °C
Conc.:
1 g/L

Any other information on results incl. tables

Individual results of duplicate measurements were:

#1       23.83 ± 0.15 mN/m.

#2       26.60 ± 0.16 mN/m

Taking into account the different values and their nominal uncertainty, the uncertainty of the mean value (25.2 mN/m) is estimated as 1.5 mN/m.

Applicant's summary and conclusion

Conclusions:
The surface tension of a 1 g/L aqueous solution of the test substance is 25.2 ± 1.5 mN/m at 25 °C.
Executive summary:

The surface tension of the test substance was determined according to the OECD Guideline 115 using the plate method. At 25 °C, the surface tension is 25.2 +/- 1.5 mN/m.
